Application filed September To all whom it may concern:

Be it known that I, SIGMUN'D SACHS, a citizen of the United States, anda resident of the Bronx, county of Bronx, and State of New York, haveinvented certain new and useful Improvements in Automatic. Stands forElectric Irons, of .which the following is a specification.

The objects of this invention are toprovide a stand for supporting anelectric iron which will combine with the functions of a support, asimple and practical means for automatically cutting ofi the heatingcurrent when the iron is not in use.

Various other objects of the invention and the novel features ofconstruction, combinations and relations of parts by which the same areattained will appear in the course of the following-specification.

In the drawing accompanying and forming part of the pecification, theinvention is illustrated in a practical commercial embodiment but assuch illustration is primarily for purposes of disclosure, it should beunderstood that the structure may -be varied and modified withoutdeparture from the broad spirit and scope of the invention ashereinafter defined and claimed.

Figure 1 is a brokenperspective view illustrating the stand in use andshowing the one continuous cord circuit from the supply outlet throughthe automatic switch in the stand to the iron.

Figure 2 is a top plan view of the stand partly broken away toillustrate the switch and connections.

Figures 3 and 4 are longitudinal and transverse sectional views of thestand, the

latteras taken on line 4-4 of Figure 2.

Figures 5 and 6 are sectional and perspective detail views of themovable and stationary contact elements.

In the illustration 5 designates an iron of conventional design suppliedwith heat ing current by a flexible cord 6 provided with a plug 7engageable with an ordinary outlet fixture 8.

As shown in the general view, the stand for the iron is interposed inthe cord circuit.,-at a point to provide adequate length. of cord forconncction'with the outlet fixture and to provide sufficient freedom forordinary ironing purposes. Where, however, greater than ordinary freedomis required, the iron may be. temporarily disconnected from the cord bysimply detach- 6 1924. Serial No. $38,238.

ing the plug 9 which'connects the cord with the terminals of the iron.

The stand is shown in the form of a base plate 10 of the general shapeof the iron and having upstanding side flanges 11 for guiding the ironto a proper seat thereon. For ventilation purposes, this base plate issupported in raised position, by a foot or lug 12 at the front and by adependent wall 13 at the rear. This latter is continued around to form aswitch chamber which is closed at'the bottom by a cap plate 14 removahlysecured in place by screws 15.

Within the switch chamber and shown as secured to the under side of thebase plate at 16 is an insulating base 17 carrying at its under side apair of spaced contacts 18, 19 arranged to be bridged by a contact 20carried by a plunger 21 proiecting up through a guide passage 22in theinsulating base and supporting base plate. This plunger is shown aspositioned about midway or on the longitudinal center line of the standadiacent the open rear of the same so as to be surelv engaged by theiron even though it be carelesslv placed or not fu l entered over thestand.

The movable contact is shown in the form of an annular washer having lus. 23. turned in ard over a disc 24 of ins a ing m te fixe on theplunger and the lower.

end of the plunger is shown as of red ed diameter and operating througha guide opening 25 in the can plate.

A tomatic en a ement of the movable conta t with the ti ed contacts is e'e terl in the illnstration hv a bowed spring 26 having a hearing on thecap plate and perforated in i s intermedia e portion to receive thereduced part of the plunger and engage I with the shoulder 2 on theplunger.

In. the rear wall of the switch chamber ofthe stand. insulating bushin s28. 29 are mounted for passage of the single length of conductor cordwhich is all that is necessarv to use in this invention.

The stand can be wired hv simply removing the cap plate 14 and threadingthe cord to the binding screw 34 of the other stature,

tionary contact 19. The stand is tapped intothis cord circuit at-such anintermediate point as to leave plenty of cord to reaclrthe outlet and anample length of the cord for use of the iron.

Because of its simplicity, few parts and manner in which it isv bracedby the convergent side flanges l1 and the front and rear supports, thestand can be made quite light in weight. solidity and stability isdesirable in a support of this character, a relatively heavy stud 35 maybe extended down from the central portion of the top plate to serve bothas a centrally located weight and as an extra foot for supporting theintermediate portion of the top plate. This foot prevents the top fromsagging even when made of quite thin metal andprevents injury even ifthe iron-be dropped heavily onto the stand. By thus taking the shocksthis toot serves to protect the switch strucli' additional solidity orfinity is desired, the stand may be secured fast upon the ironing-board,table or other support by means of a suitable anchor screw extended upthrough the support into a screw seat 36' provided in the dependentweight and brace 35.

The switch plunger operates with a straight u and downv motion andbeingguided at 0th top and bottom, shifts easily either with the weightof the iron to break the circuit or under impulse of the spring to closethe circuit.

The guide flanges 11 usually will stand higher than the tip of theswitch plunger serving as guards to prevent an object from falling overthe stand and breaking the circuit and also as raised supports uponwhich the iron may be rested in case it should be found desirable toallow the iron to heat for a while, supported on the stand. lheinsulating washer which .carries the movable switch contact maybe fixedon the plunger by a screw threadedconnection, as

indicated in Figure 5, and as this plunger is free to, rotate it'mayturn, in the use of the stand, to presentiresh contact surfaces to thestationary switch elements.

All of the switch arts are wholly enclosed within the switch chamber inthe I bottom of the stand and so protected from mechanical injury, dust,moisture, etc., and the user of the device is fullyprotected against anypossible injury; The convergent guardfianges uide the iron squarely intoposition over t e switch plunger with- As a certain degree of massespendent walls at the rear of the same forming a chamber and support, aremovably secured cover plate closing said chamber, an

insulating) base on the under side of the spring engaged over the lowerportion of i the spindle hearing at its ends against the inside of thecover plate and operating to thrust the spindle upwardly to normallyhold the plunger contactengaged with the stationary contacts.
